International Classification:

G01N 2134

US Classification:

250444

Abstract:

An X-ray table has a cassette holder for receiving an X-ray film cassette and releasably retaining it generally adjacent the lower surface of the table top and at least one collapsible guard rail assembly supported for movement between raised and lowered positions. The guard rail assembly includes a hollow elongated top rail supported above the plane of the table top in said raised position and disposed adjacent an associated side edge of the table top immediately above the cassette holder in said lowered position. The support members which carry each top rail and the means for retaining it in its raised position are substantially wholly disposed within the confines of the hollow top rail in its lowered or collapsed position.

Abstract:

A cassette having a rectangular body made from plastic material including a marginal frame bounding a pair of film compartments separated by a radiation barrier and opening outwardly through opposite faces thereof. A pair of covers also made from plastic material and hingedly connected to opposite ends of the frame provide closures for the two film compartments. Each cover has a peripheral bead which is received within an associated groove in the frame when the cover is in a closed position. A U-shaped strip of magnetic material is sealed within each bead and cooperates with an associated U-shaped strip of magnetized material sealed within the body to releasably retain the cover in its closed position. The bead and groove further cooperate to comprise a light barrier for an associated film compartment.
